Application
L-谷氨酸脱氢酶可用于催化异柠檬酸转化为α-酮戊二酸和二氧化碳。
Biochem/physiol Actions
这种酶的哺乳动物形式，包括这种牛形式，可以使用 NADP (H) 或 NAD (H) 作为辅酶。 L -谷氨酸脱氢酶在哺乳动物代谢中起着独特角色。该酶催化的逆向反应是氨与 α-淀粉结合的唯一途径。-α 的碳原子-因此，羧酸是哺乳动物中从头合成氨基酸的唯一来源。
牛酶的特点有三组属性：
L-谷氨酸脱氢酶催化谷氨酸转化为 α-酮戊二酸 。
牛酶的特点有三组属性：
- 具有可逆的浓度依赖性结合，产生较高分子量形式。
- 形成紧密的酶-还原型辅酶-底物三元复合物，其解离速率调节稳态反应速率。
- 表现出各种各样的影响，从结合的任何编号核苷酸修饰。

The tissue distribution, the subcellular distribution in liver, and the developmental patterns of cysteine:alpha-ketoglutarate aminotransferase (CAT) and 3-mercaptopyruvate sulfurtransferase (MPST) activities were determined in rats of the Sprague-Dawley strain. CAT activity was highest in heart and liver, whereas MPST activity
